Greece's leaders have received a guarded welcome to their reported proposals for a debt deal, ahead of crunch talks with EU creditors.

After a meeting in Rome with Greek PM Alexis Tsipras, Italian PM Matteo Renzi said his country would "give Greece a hand" without always agreeing with it.

Greek Finance Minister Yanis Varoufakis has reportedly suggested a new deal for exchanging debt with bailout creditors.
